I think platforms have gotten to a complexity where starting from a clean state isn't as easy anymore. Just look at fuschia, I know it's been in "early" development since at least 2013 and there's not much to show for it. Things get A LOT more complicated when you add localisation, accessibility, UI and all the other things we take for granted.
